This roundup is designed to report which compiler and library implementations support the standard well. (compiled and edited by Herb Sutter)

Command line driven C and C++ compiler that generates platform specific and C compiler specific C as its object code. Includes almost all of the language features that the ANSI/ISO C++ committee agreed upon for Standard C++.

Successor of Symantec C++ with support for Win32, Win16, DOS16, and DOS32. Command-line compiler is freely available.

Lists free C and C++ compilers, cross-compilers and interpreters for a wide variety of operating systems (including embedded systems).

A "Scalable C++" compiler that includes a variety of user-selectable language feature combinations to meet specific needs. The C++ Compilers conform to the ANSI/ISO C++ standard. Ranging from bare-bones C up through full-blown ANSI C++, Green Hills Op...

The HP C/aC++ Developer’s Bundle provides the tools for compiling, linking, and debugging C and C++ programs on HP-UX 11i (v1 and v2) on the HP Integrity and HP 9000 systems.

A portable C/C++ preprocessor supporting several compiler-systems on UNIX and DOS/Windows. MCPP supports C99 and C++98 as well as C90. Also provides a validation suite which tests the C/C++ preprocessor comprehensively.

Provides an opportunity to take full advantage of IBM C/C++ compiler products and meet with people who want to maximize their productivity and pass on their knowledge to others.

Optimizing compiler for Intels 32-bit and 64-bit processors. Produces executables that are source and object code compatible with Microsoft Visual C++. For Linux and Windows. Also Fortran and EFI byte code compilers.

An aggressive open-source compiler for C and C++. It specializes in interprocedural optimization/analysis and supports runtime and offline optimization "in the field" as well.
